Ok but I’d like to see an analysis of why humans are so resistant to change. It’s such a universal characteristic that there must be some sort of advantage to it, right? What is that advantage?
In my experience, in general, we are not!
We are resistant to change only when someone else is trying to impose a burden over us without a clear picture of how such burden is going to profit us. I don't think we need any study to understand why!
I recommend book "Seven and a Half Lessons About the Brain" by Lisa Feldman Barrett where she talks a bit more about that.
Disadvantage is you ruin your life by living a repetitive life. Probably the #1 regret in death bed.
For millions of years of evolutionary history the main concern was making it alive, having a family, building a homestead, putting food on the table, keeping dangers (including enemies) off, and so on.
If you had those things, the "current situation" was good. They didn't aspire to get a promotion, start a startup, or become a travel vlogger.
The "novelty seeking" has been the exception, and even the novelty seekers didn't consider it a primarily purpose of one's life.
a) there was once more of an advantage, back when change had significant impact upon survival
(horses are notorious for being change-averse, but ours are, at least for equines, fairly novelty-tolerant; I ascribe this to their having learned, via experience, that the people are always trying new stuff, and some of it is more fun and some of it is less fun, but none of it has any impact on whether the food in particular, and safety in general, is available)
b) > I believe what really happens in history is this: the old man is always wrong; and the young people are always wrong about what is wrong with him. The practical form it takes is this: that, while the old man may stand by some stupid custom, the young man always attacks it with some theory that turns out to be equally stupid. —GKC
When you try to bring something that ease their life without introducing huge additional cognitive load, or threats to whatever they feel like an island of stability in the chaos of life, they will certainly appreciate it and praise you for coming with it.
Also there is a acceptation threshold of how many breaking regressions are induced as an unintended side effect, no matter how brilliant the change proposed is for its intended purpose. Especially if change come in a top-down condescending know-better-than-you approach, rather than a "let’s take time together to improve your daily experience."
The old people might be wrong (at least as much of the rest of humanity), but they did survived for some time. So to improve survival rate of younger people, if the environment is stable enough, as clumsy as elder approach might be and all other meaningful information let apart, imitation seems a safer bet than trying random audacious moves with unknown results. Note that it’s all supposing much to comfort a rather conservative under a pseudo-scientific form of social darwinism. I wouldn’t agree to make that this could taken as a well balanced perspective.
(It’s just one angle of looking at this, of course, it may not always apply, but it could explain counter-intuitive instances of resistance to change.)
Historically, this dynamic (=set of tradeoffs) fails most often in turbulent times ("chaos is a ladder" trope from GoT) but I suspect that, (in addition to the opiate of tech) worldwide literacy today (not to mention ease of survival) confounds the youthful naive.
i.e. most young people today have been indoctrinated about how to identify locally bad social theories (in the abstract!!), plus the smarter ones don't get their kooky theories weeded out violently enough for the unfunny ones to evolve in a meaningful way uh memetic darwinism?
(But perhaps you can have a theory of how IT kills unironic memes like machine guns the aristocratic infantrymen of WWI)
Watch out for unusually literate/numerate AND lawless places of formativity. I supppose..
(Ukraine, soon Taiwan, middle east in the intraorganizational (not individual) level once the Arabs/Hamas level up in organizational sophistication )
Something to think about: where are the lasting new social abstractions from kibbutzim? What the hell goes on in Adam Newman's head, has he ever published his conjoined triangles (<<Silicon Valley>>)
But I'll give you the most useful answer, which is also perhaps the most boring:
Because people have more important things to do.
